[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1, please refer to Figure 1 As shown, a method for adjusting the electricity purchase structure described in this embodiment includes the following steps: S1. Collect historical electricity purchase information of the user end, wherein the historical electricity purchase information includes historical electricity purchase structure, electricity purchase cost and user electricity consumption behavior information, and classify the user end according to the historical electricity purchase information based on preset classification conditions to obtain multiple electricity consumption types; S2. Build a user electricity purchase model according to the electricity consumption type and the corresponding historical electricity purchase information, bind the user electricity purchase model with the corresponding user terminal and store it in a database, wherein the database includes an information library, an information storage library and a protection network, the protection network includes multiple dual ports, multiple wandering factors and multiple wandering trajectories, and the user terminal is connected to the database through the dual ports to obtain the association relationship between the database and the user terminal; S3, based on the wandering factor and the corresponding wandering trajectory, determine the security state of the database and control the opening and closing of the dual ports to prevent the user end from using an unsafe user power purchase model, and use the user power purchase model in the database corresponding to the security state that meets the preset conditions as a security model; S4. Adjust the electricity purchasing structure of the user side through the security model.

[0018] As described in the above steps, the historical power purchase structure of the user end is collected through big data. The user end here can be an enterprise power end or a retail power end. Then, the power purchase cost corresponding to the historical power purchase structure is obtained, and the user's power consumption behavior information is obtained at the same time. The historical power purchase structure, power purchase cost and user power consumption behavior information of the user end are used as historical power purchase information. The user's power consumption behavior information is the user's power consumption habits. For example, a large amount of electricity or a small amount of electricity may be used in a certain period of time. A single user end may have multiple historical power purchase structures. Due to seasonal and life reasons, there will be changes in the power purchase structure, and the corresponding power purchase cost is also different. After obtaining the historical power purchase information, the user end is classified according to the historical power purchase information based on the preset classification conditions to obtain multiple power consumption types. The preset classification condition here is the range of the corresponding historical power purchase information. The same historical power purchase structure, the power purchase cost within the preset range, and the power consumption behavior information within the preset conditions are taken as one category to obtain multiple power consumption types, so that the common power purchase structure can be adjusted in the subsequent user ends corresponding to the same power consumption type.

[0019] In one embodiment, the step S2 of building a user electricity purchase model according to the electricity consumption type and the corresponding historical electricity purchase information, binding the user electricity purchase model with the corresponding user terminal and storing the information in the database includes: S21. Constructing the same number of timelines as the number of electricity usage types, binding the timelines to the electricity usage types, and constructing the historical electricity purchase information corresponding to the electricity usage types on the corresponding timelines to obtain a user electricity purchase model; S22, binding the user's electricity purchasing model with the user terminal corresponding to the electricity consumption type; S23, storing the user's electricity purchasing model in a database, and establishing an association relationship between the database and the user end; As described in the above steps S21-S23, each type of electricity consumption includes multiple user terminals, and the historical electricity purchasing information of the same type of electricity consumption has similar situations. Therefore, the user terminals have different electricity purchasing structures at different time lines. For example, there is a clustering situation of electricity consumption in winter and summer. Then, a user electricity purchasing model of the same type of electricity consumption is constructed. The electricity purchasing structure is the correspondence between the electricity price and the time period. For example, the electricity price in a certain time period of a day is X, and the electricity price in the other time periods is Y, or it is the correspondence between the seasonal electricity price and the time period. The user electricity purchasing model is the correspondence between time and the electricity purchasing structure. The time line is corresponded to the electricity purchasing structure as the user electricity purchasing model. Then, the user electricity purchasing model is bound to the user terminal corresponding to the electricity consumption type. The electricity purchasing structure of the user terminal with the same electricity consumption type can be managed, and then the electricity purchasing structure of the user terminal can be recommended according to time, which helps the user terminal to adjust the electricity purchasing structure. A large number of user electricity purchasing models of the user terminals are stored in the database, which has a good data preservation effect.

[0020] In one embodiment, the step S23 of storing the user's electricity purchasing model in a database and establishing an association relationship between the database and the user terminal includes: S231, formulate a database, the information storage library is located in the middle of the information storage library, and the information storage library and the information library include a wandering layer; S232, in the wandering layer, using dual ports as wandering stationary points, respectively formulate wandering trajectories of a plurality of wandering factors, and the wandering factors move in the corresponding wandering trajectories; S233, storing the user electricity purchase model in the information storage database, and connecting the database and the user end based on the dual port to obtain an association relationship; In one embodiment, the information storage library is located in the middle of the information storage library, and the step S231 of including a wandering layer between the information storage library and the information library includes: S2311, determine an information library, divide an information storage library in the middle of the information library, and use the storage space between the information storage libraries as a wandering layer; S2312, placing multiple wandering factors in the wandering layer, and establishing multiple dual ports on the information base, wherein the dual ports include a first port and a second port; S2313, the first port and the second port are connected to each other in communication, the first port is outside the information base, and the second port is inside the information base, so as to obtain a protection network; As described in the above steps S231-S233 and S2311-S2313, the information library is a storage library and database for storing user electricity purchasing models. An information storage library is divided out in the middle position of the information library. The information storage library is specifically used to store user electricity purchasing models. In order to ensure the security of the storage of user electricity purchasing models, a protection net is set up here. A plurality of wandering factors are invested in the wandering layer between the information storage library and the information library, wherein the wandering factor is a port that can move in the set information track (wandering trajectory), and the wandering layer is the storage space between the information storage library and the information library. A plurality of dual ports are set on the information library, wherein the dual ports include a first port and a second port, wherein the first port is outside the information library and the second port is outside the information library. Located inside the information database, the first port is used to connect the information database with the external user end for communication, and is used to obtain the user's electricity purchasing model. The second port is used to determine abnormal conditions in the information database. The first port and the second port are connected for communication, and when the second port determines that the information database is abnormal, the first port is linked to react, the first port is closed, and the electricity purchase model is no longer provided to the user end, so as to avoid the unsafe electricity purchase model from providing wrong information to the user end, resulting in the wrong adjustment of the user's electricity purchase structure, and ensure the accuracy of the electricity purchase structure adjustment. The protection network is used to prevent the external network from intruding into the database, and then the user's electricity purchase model is stored in the information storage library. Based on the dual ports, the database and the user end are connected to obtain an association relationship.

[0021] In one embodiment, the step S2312 of placing multiple wandering factors in the wandering layer and formulating multiple dual ports on the information base includes: S23121. Determine the number of electricity usage types, and place multiple wandering factors in the wandering layer that are equal to the number of electricity usage types; S23122. Establishing multiple dual ports with the same number as the power consumption type in the information base; S23123, corresponding to the multiple dual ports, duplicate the same dual ports respectively, and bind information between the two dual ports and a wandering factor; In one embodiment, the step S232 of respectively formulating the wandering trajectories of a plurality of wandering factors using the dual ports as wandering stationary points in the wandering layer, and moving the wandering factors in the corresponding wandering trajectories, comprises: S2321, dividing the information storage library into multiple sub-data areas according to the number of electricity usage types; S2322, binding the two dual ports and a wandering factor after information binding to a sub-data area; S2323, the corresponding bound sub-data area uses the dual ports as wandering station points to formulate a wandering trajectory, and the wandering factor moves in the corresponding wandering trajectory; As described in the above steps S23121-S23123 and S2321-S2323, the number of electricity types is determined, and the number of electricity types is the same as the number of user electricity purchasing models. After the number of electricity types is determined, multiple wandering factors with the same number as the electricity types are placed in the wandering layer, and multiple dual ports with the same number as the electricity types are formulated on the information database. The same dual ports are copied for the corresponding multiple dual ports, and information is bound between two dual ports and a wandering factor. After that, the information storage library is divided according to the number of electricity types to obtain multiple sub-data areas. Subsequently, the user electricity purchasing models are stored one-to-one in the sub-data areas respectively, and the two dual ports and a wandering factor after the information is bound are bound to a sub-data area. In this way, the two dual ports and a wandering factor can protect the user electricity purchasing model in a sub-data area, and the corresponding bound sub-data area uses the dual ports as wandering station points to formulate wandering trajectories. The wandering factor moves in the corresponding wandering trajectory, which can better protect the data security of the user's electricity purchasing model. When the electricity purchasing model is not obtained through the dual ports, but through other unauthorized ports, the wandering trajectory will change (because the wandering trajectory is constructed with the dual ports as wandering stations, the wandering trajectory is not fixed. According to the sub-data area for obtaining information and modifying data, the wandering trajectory bound to the sub-data area can automatically capture the port of the corresponding sub-data area in the database, and the natural wandering trajectory will change). Then the wandering factor will change, which can be prompted to the second port through the wandering factor, and the first port can be closed through the second port (there is no need to close all ports, and it will not affect the normal use of other types of electricity users), avoiding the user end from using unsafe user electricity purchasing models for adjustment and avoiding the activation of wrong electricity purchasing structures; In one embodiment, the step S3 of determining the security state of the database based on the wandering factor and the corresponding wandering trajectory and controlling the opening and closing of the dual ports to prevent the user end from using an unsafe user power purchase model, and using the user power purchase model in the database corresponding to the security state that meets the preset conditions as the security model includes: S31, the safety status of the user's electricity purchasing model is obtained by prompting the second port through the wandering factor. When the wandering trajectory changes, it does not meet the preset conditions, and the wandering factor prompts an unsafe state. The wandering factor prompts the unsafe state to the second port, and the first port is closed through the second port; S32, when the wandering trajectory does not change, it meets the preset conditions, the wandering factor prompts that it is in a safe state, and the user power purchase model in the safe state is used as a safe model; As described in the above steps S31 and S32, since the wandering trajectory is constructed with dual ports as wandering stationary points, the wandering trajectory is not fixed. According to the sub-data area for obtaining information and modifying data, the wandering trajectory bound to the sub-data area can automatically capture the port of the corresponding sub-data area in the database, and the natural wandering trajectory will change. The second port is prompted by the wandering factor to obtain the safety status of the user's power purchasing model. When the wandering trajectory changes, it does not meet the preset conditions, and the wandering factor prompts an unsafe state; when the wandering trajectory does not change, it meets the preset conditions, and the wandering factor prompts a safe state. The user's power purchasing model in the safe state is used as a safe model, and then the power purchasing structure is recommended to the user end through the safety model. When the user end determines the power purchasing structure, the adjustment of the power purchasing structure is completed.

[0022] Example 2, please refer to Figure 2 As shown, a power purchase structure adjustment system described in this embodiment includes: A collection module is used to collect historical electricity purchase information of the user end, wherein the historical electricity purchase information includes historical electricity purchase structure, electricity purchase cost and user electricity consumption behavior information, and classify the user end according to the historical electricity purchase information based on preset classification conditions to obtain multiple electricity consumption types; The storage module is connected to the acquisition module and is used to construct a user electricity purchase model according to the electricity consumption type and the corresponding historical electricity purchase information, and to bind the user electricity purchase model with the corresponding user terminal and store it in a database, wherein the database includes an information library, an information storage library and a protection network, and the protection network includes multiple dual ports, multiple wandering factors and multiple wandering trajectories. The user terminal is connected to the database through the dual ports to obtain the association relationship between the database and the user terminal; The analysis module is connected to the storage module and is used to determine the security state of the database based on the wandering factor and the corresponding wandering trajectory and control the opening and closing of the dual ports to prevent the user end from using an unsafe user power purchase model, and use the user power purchase model in the database corresponding to the security state that meets the preset conditions as a security model; The adjustment module is connected with the analysis module and is used to adjust the electricity purchase structure of the user end through the security model.
